[Bug tree-optimization/35144] New: [4.3 regression] ICE in generate_element_copy

[jakub at gcc dot gnu dot org]

struct A
{
  int baz ();
};

typedef int (A::*P) ();

struct B
{
  B ();
  int foo (P x, int y = 0);
};

struct C
{
  typedef int (B::*Q) (P, int);
  void bar (Q x) { c = x; }
  Q c;
};

extern C c;

B::B ()
{
 c.bar ((C::Q) &B::foo);
}

ICEs with:
internal compiler error: in generate_element_copy, at tree-sra.c:2603
at -O and above on x86_64-linux (-m64 as well as -m32).
Revision 126202 still works, 126654 already ICEs.
